(NaturalNews) It used to be that most people ordering from a fast food restaurant worried about whether or not their fries would be served cold. Eventually, people started to fear that they might chomp into the likes of a chicken head found in their nuggets or eat breads containing the same material that is found in yoga mats.

However, the latest batch of news will have you questioning the possibility that workers are running a meth lab at your favorite fast food chain.

It might sound like something out of a Breaking Bad episode, but it's true: two men at a Cedar Rapids, Iowa, Taco Bell were recently found to be running a meth lab from within the fast food restaurant. After remnants of meth were found by officials in that location's Taco Bell utility area, the restaurant was closed and Christopher Adam Matous, 31, and Kent Jerome Duby, 56 were charged with conspiracy to manufacture methamphetamine. Furthermore, Matous was also charged with meth possession.

We understand that two people, one an employee, entered our franchisee's restaurant illegally, allegedly possessing suspicious items. Both we and our franchisee find this completely unacceptable. Our franchisee has been cooperating with Cedar Rapids Police to investigate this isolated incident. Although the suspicious items found in the restaurant were not used in the kitchen, the employee has been terminated and our franchisee is considering pressing criminal charges. The restaurant will reopen after it has been sanitized and inspected by the Health Department.

It's a good thing that they plan to sanitize and hold an inspection. However, the question of what was happening all along remains. While these men dabbled in making meth, who knows what else their hands were on. They -- or at least the one employee involved -- could have been making and handing customers their burritos, re-stocking napkins, and touching cups, all of which could have had traces of meth on them and then made their way into customers' mouths. Not cool, Taco Bell.

At different location, another negative Taco Bell incident surfaces

Unfortunately for the restaurant chain, this news precedes another disturbing find involving the discovery of an acrylic fingernail in their nachos. In this instance, a Lake Wales, Florida, couple decided to indulge in a late-night Taco Bell snack. Kailynn Roland made the discovery, which was embedded in the layers of fried beans and nachos.

"It's gross. I puked," she said.

The couple says they are awaiting more accountability and an apology from the chain beyond the $40 in gift cards they were offered. While Taco Bell says they accepted the gift cards, the couple maintains they did not.

As for eating at a Taco Bell again, Roland says, "Probably never again, and if I do eat at a Taco Bell, it will not be at this location."

Finding the good in the bad: fast foods chains that seem to have their act together

In the midst of such findings, which tend to cast a bad light on fast food chains everywhere, there are those that have stepped up to ensure that unhealthy ingredients like meth, additives, and other harsh chemicals stay out of their food.

In recent times, Chipotle has announced their GMO-free move, Panera is working on removing certain unhealthy ingredients from more than 150 foods, and Subway -- despite their recent debacle in which weight loss spokesperson Jared has been charged with child porn -- said it would remove azodicarbonamide from their breads.

Azodicarbonamide is the same material found in yoga mats and the rubber parts of sneakers. When broken down during the baking process, it has been linked to causing blood and lung cancers in mice.
